SPECIFICATION forming part of Letters Patent No. 7 80,901, dated January24, 1905.

Application nea July 29, 1904. serial No. 218,715.

To cir/ZZ whom, 7311' may concern,.-

Be it known thatI, HENRY MULL, a citizen of the United States, residingat Ashland, in the county of Clark and State of Kansas, have invented anew and useful Plow, of which the following is a specification.

This invention relates to implements forv tilling the soil, and it hasspecial reference to an improved plow which shall be adapted to loosenand to break the surface soil preparatory to the planting of the crops.

In large sections of the country it is found that the surface soil willbe completely dried out by the hot and dry winds, while acomcomparatively short distance below the surface moisture will befound. By deep plowing the soil will be turned over and the moistportion will be exposed to the drying iniiuence of the atmosphere,making it impossible for seeds planted therein to germinatesuccessfully. To overcome this difficulty, it has become common to breakthe surface soil prior to planting by ymeans of disk harrows and similarimplements; but this method of operation involves heavy and hard labor.

The object of the invention is to enable soil of they characterdescribed to be successfully tilled by raising the surface thereofl andpermitting it again to drop, thereby breaking the clods anddisintegrating the soil to prepare it for planting, this beingaccomplished by the use of the plow which is thesubject of the presentinvention.

With the ends above set forth in view the invention consists in theimproved construction and novel arrangement and combination of parts,which will be hereinafter fully described, and particularly pointed outin the claim.

In the accompanying drawings has been illustrated a simple and preferredform of embodiment of the invention, it being understood, however, thatno limitation is necessarily made to the precise structural detailstherein exhibited, but that the right is reserved to any changes,alterations, and modilications to which recourse may be had withoutdeparting from the spirit or sacrificing the eiiciency of the same.

In said drawings, Figure 1 is a plan view of a plow constructed inaccordance with the principles of the invention. Fig. 2 is a bottom planview of the same. Fig. 3 is a perspective view of the plow foot or frogand the lower part of the standard to which it is attached. Fig. 4 is atransverse sectional view taken on the line 4 4 in Fig. 1. Fig. 5 is aplan view showing a modified form of the plow-blade. Fig. 6 is a planview showing a modified form'of the blade which is usually employed ingangs. Fig. 7 is a longitudinal sectional detail view of the device asshown in Fig. l. l

Corresponding parts in the several figures are indicated by similarcharacters of reference.

An ordinary plow-standard (shown at 1)'is provided at the lower endthereof with a horizontally-disposed heel-piecaor landside 2, the rearend of which is connected with a standard by means of a brace 3.

Upon the front end of the landside 2 is mounted and permanently secureda baseplate which I call the frog 4, said frog consisting of a steelplate firmly secured in position upon the point of the landside andhaving laterally-extending wings 5, said wings being provided withperforations 6 6 for the reception of bolts.

7 7 designate the wings of the plow, which consist of steel platesrhomboidal in shape and provided at both ends with bolt holes orperforations 8 8, corresponding with the perforations 6 in the frog,with which the said wings or plow-blades may thus be reversiblyconnected, said blades being provided with cutting edges at both theirupper and their lower edges.

. 9 designates the point having perforations 10. The point is adapted tooverlap the meeting ends of the blades 7 7 and to connect it with thelatter and with the frogs by means of bolts 11 passing through theperforations 10, 8, and 6 in the point, the wings, and the frog,respectively. The point 9 is provided on its under side with a pocket l2for the reception of the lower extremities of the wings or blades. Itwill thus be seen that the proximate ends or points ofthe wings orblades will be protected not only by being inserted IOO into the pocketof the plow-point, but also by being overlapped by said point upon theupper side and by the frog upon the under side. In addition to beingsecured upon the frog by means' of the bolts 1l the wings are braced andsecured by means of cross bars or braces 13,l connecting said wings orblades with the bolt 14,which connects the standard 1 with the landside2. l

In operation the wings orblades of the plow are set at any desiredupward and rearward inclination, which is determined by the position ofthe frog, which may be regulated by tilting the landside more or lesswith relation to the stand ard. The plow-point and the edges of thewings or blades being suiiiciently sharpened, the plow whenv draft isapplied will readily cut into the soil, the surface of which will belifted and elevated and caused to drop over the rear edges of theblades, being thus sufciently broken and .disintegrated I desire it tobeparticularly understood that the soil is not turned, but merely brokenby the action of this device. Thus when the land is in stubble thestubble will furnish a valuable mulching for the land, and it will befound extremely valuable in preventing the seed subsequently plantedfrom being1 blown out of the ground by the high winds which are soprevalent in sections of the country for which this improved plow isspecially intended. When the seed is drilled into the soil, it will bedeposited in a comparatively moist stratum of the latter, which willinsure its early and successful germination.

Under the modiiication'illustrated in Fig. 5 of the drawings the wingsor blades, here designated 15, and the point 16 of the plow are 'madefrom a single piece of steel provided with suitably-disposedperforations 17 for the reception of the bolts, whereby this plow may bebolted directly upon the frog connected with the standard. Thisconstruction is less expensive, inasmuch as the special formation of thepoint with a pocket or receptacle in its under side is thereby avoided.

In Fig. 6 another modification has been illustrated,whereby theconstruction of the plow is specially adapted for use in gangs of anydesired number. Under this modilication one of the wings, heredesignated 1S), of the plow is made considerably shorter than the otherwing, 20, said wings being formed integral with each other and with thepoint 21. With this construction a gang of any desired number of unitsmay be used, the short blade ol each unit being disposed to overlap thelong blade of the unit in front thereof, as will be readily understood.

l desire it to be understood that this improved plow may be made indifferent sizes and that it may be utilized as a walking, a riding, or agang plow within the scope of the invention.

Having thus described the invention, what is claimed is- In a plow ofthe class described, the combination with a landside having a frog whichconstitutes a supporting member, of wings,

forming moldboards,supported upon and completely overlapping said frog,an earth-engaging point superimposed upon said wings and having in itsunder side a recess accommodating thel points of the wings, andconnecting-bolts extending through the frog the wings and the point.

In testimony that I claim the foregoing as my own l have hereto aiiixedmy signature in the presence of two witnesses.
